I need help :/ i have five questions

IrinaK [193]

Answer:

Step-by-step explanation:

1. The given equation is:

$\frac{3}{5}{\times}\frac{4}{5}$

Multiplying both the terms, we get

$\frac{12}{25}$

Option A is correct.

2. The given equation is:

$2\frac{1}{3}{\times}\frac{3}{4}$

Converting the improper fraction into the mixed fraction,

$\frac{7}{3}{\times}\frac{3}{4}$

= $\frac{7}{4}$

Option C is correct.

3. The given equation is:

$\frac{3}{16}{\times}\frac{4}{21}$

Multiplying both the terms, we get

= $\frac{1}{28}$

4. The given equation is:

$3\frac{8}{9}{\times}4\frac{4}{5}$

Converting the improper fraction into the mixed fraction,

$\frac{35}{9}{\times}\frac{24}{5}$

= $\frac{56}{3}$

5. One package contains= $5\frac{1}{4}=\frac{21}{4}$ pounds of raisins.

$4\frac{2}{3}$ packages contains= $4\frac{2}{3}{\times}5\frac{1}{4}$ pounds of raisins.

= $\frac{14}{3}{\times}\frac{21}{4}$

= $\frac{49}{2}$

Therefore, the baker used $\frac{49}{2}$ pounds of raisins.

Composition function rule (f○g)(x) = f(g(x))
Given the separate functions: $f(x)=2x+1$ and $g(x)=x^2$

$(f\circ g)(-5)\rightarrow\text{ Composition Function Rule}\rightarrow f(g(-5))=2((5)^2)+1$
$\rightarrow2(25)+1=50+1=51$

In a first-order decomposition reaction. 52.3% of a compound decomposes in 8.6 min. How long (in min) does it take for 80.3% of

rusak2 [61]

Answer:

13.20 min

Step-by-step explanation:

Rate of the reaction is a measure of the rate of decomposition of the compound.

Rate (R) = Concentration (C) ÷ time (t)

C1/t1 = C2/t2

C1 = 52.3% = 0.523

t1 = 8.6 min

C2 = 80.3% = 0.803

t2 = C2t1/C1 = 0.803×8.6/0.523 = 13.20 min (to 2 decimal places)

Write a function that models each variation.

Leno4ka [110]

Answer:

z = 2.7x/r²y

Step-by-step explanation:

z = kx/r²y

½ = k × ⅓ ÷ (3² × ⅕)

½ = ⅓k × 5/9

k = 27/10 = 2.7

z = 27x/10r²y

z = 2.7x/r²y
